New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:

Ferrari IPO may turn out to be good news for enthusiasts

Sergio Marchionne's strategy to spin off Ferrari from FCA and make the Italian automaker a publicly traded company has been met with ire from a vocal contingent of enthusiasts ever since rumors about the plan began to surface a few years ago. Some of these particularly pessimistic automotive pundits have voiced fears that with stockholders in the mix, it would not only spell the demise of the exclusive Italian supercar maker as we know it, but would in fact "ruin" the company. Call me dense, but I fail to see what the issue is. That isn't to say that I don't understand what's causing the fear. When profitability becomes a higher priority for a brand that's historically relied on exclusivity to keep its products in the highest echelons of desirability, there's a high potential for internal philosophical conflict. And then there are concerns about the sorts of products that Ferrari might develop that aren't the high-performance sports cars that the brand is known for. But individuals with those apprehensions seem to forget that Ferrari has already lent its name to a multitude of things that are not LaFerraris, 488 GTBs, or F12 Berlinettas, including clothing, headphones, and even laptops. But let's assume for a moment that the core anxiety is about future vehicles – including the unspeakable notion that Ferrari might develop an SUV. Why wouldn't Ferrari build an SUV, especially after seeing how incredibly successful that endeavor has been for Porsche? I think it's likely that Ferrari will put engineers to task creating some sort of crossover or high-rolling cruiser with room for the whole family at some point in the near future. And why wouldn't it, after seeing how incredibly successful that endeavor has been for Porsche? After all, the Cayenne accounted for more US sales in 2013 than the Boxster, Cayman, 911, and 918 combined, and it only gave up about a thousand units of sales last year to make room for the Macan crossover, the latter of which Porsche sold nearly as many of as it did Boxsters and Caymans. People want these vehicles, and they're willing to pay quite a bit of money for them. If we use Porsche's recent trajectory as a foreshadowing metric for what's in store for Ferrari, the future actually looks pretty good. After all, those SUV sales keep plenty of cash in Porsche's coffers for the low-volume projects that we enthusiasts love, like the 918 Spyder and the 911 GT3 RS.

Investigators blame speed in fatal Paul Walker crash

When the tragic news first came in that actor Paul Walker had been killed in a car crash, family, friends and fans were left searching for answers. They now have at least one key question answered, with the Los Angeles County Sheriff's Department blaming "unsafe speed" for the fatal accident.
According to a statement released by the LACSD, "Investigators determined the cause of the fatal solo-vehicle collision was unsafe speed for the roadway conditions". The investigation into the November, 2013 crash determined that Walker's 2005 Porsche Carrera GT had been driven by his business partner and racer, Roger Rodas, at speeds between 80 and 93 miles per hour - less than the 100+ mph initially suspected, but still far too fast for the road on which they were traveling, which carried a posted limit of 45 mph.
In the investigation into the death of the Fast & Furious star and his friend, some people were quick to finger the Porsche in which they were riding as the culprit. The Carrera GT does, after all, have the reputation of being a notoriously difficult car to control. But after an exhaustive investigation, law enforcement officials in California have vindicated the car and dismissed any mechanical fault as the cause of the accident.
